[0008] There are two support rollers, which are respectively arranged on the front and rear sides of the base and are respectively located on the front and rear sides below the packaging film, and the packaging film is located on the upper side of the support rollers;

[0009] There are two suction pipes, which are respectively arranged on the front and rear sides of the base and located on the side of the support roller away from the central axis of the packaging film. The suction pipe has a suction port, which is located below the side of the packaging film. The suction pipe is connected to an external negative pressure device.

[0010] To further optimize the technical solution, the bristle ends contain magnetic materials, and further include:

[0011] A magnet is arranged on the base, located below the packaging film and below the two cleaning belts, and the magnet is magnetically attracted to the magnetic material.

[0012] Further optimization of this technical solution also includes:

[0013] an illumination lamp, arranged on the base and located above the packaging film, wherein the illumination lamp is located between the cleaning belt and the embossing roller;

[0014] The photosensitive device is arranged on the base and is located below the illuminating lamp. The packaging film is located between the illuminating lamp and the photosensitive device.

[0015] Further optimization of this technical solution also includes:

[0016] The mounting frames are provided with two, and the two mounting frames are respectively slidably arranged at the front and rear sides of the base, and the two supporting rollers are respectively arranged on the two mounting frames, and the supporting rollers are slidably arranged on the base through the mounting frames.

[0017] To further optimize the technical solution, the mounting frame is provided with a mounting hole, and the air suction pipe is inserted into the mounting hole.

[0018] Further optimization of this technical solution also includes:

[0023] 1. The two cleaning belts rotate toward the outside of the front and rear sides of the packaging film. The bristles can clean the upper surface of the packaging film, and at the same time, the packaging film is tightened and flattened toward the front and rear sides, thereby improving the flatness of the packaging film and the quality of embossing.

[0024] 2. The air suction port of the suction pipe faces upward and is opposite to the side of the packaging film. It is also located below the cleaning belt. The suction pipe can draw air to absorb some dust particles on the bristles to improve cleanliness. At the same time, the suction forms an outward pulling force on both sides of the packaging film to flatten the packaging film to the front and rear sides. The force-applying structure is wind pressure, and no hard objects come into contact with the packaging film, so it will not cause extrusion damage. It should be noted that the suction of the suction pipe causes air flow to act on the side of the packaging film. At the same time, the cleaning belt above forms a space restriction, which can increase the wind force. The support roller supports the side of the packaging film, and the packaging film will not be sucked into the suction pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0037] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] like Figure 1-9 As shown, an outer packaging embossing device includes a base 1, two embossing rollers 2 are rotatably arranged on the right side of the base 1, and a packaging film 3 passes between the two embossing rollers 2; it also includes: a cleaning belt 4, which has two cleaning belts 4, which are arranged side by side on the base 1 along the front-to-back direction and are located above the packaging film 3, and the cleaning belts 4 are arranged to rotate in a circular manner, and the two cleaning belts 4 turn in opposite directions. The cleaning belts 4 have a plurality of bristles 401, and the bristles 401 are in sliding contact with the upper surface of the packaging film 3, and the bristles in sliding contact with the packaging film 3 401 sliding direction is away from the central axis of the packaging film 3; there are two support rollers 5, which are respectively arranged on the front and rear sides of the base 1, and are respectively located on the front and rear sides below the packaging film 3, and the packaging film 3 is located on the upper side of the support roller 5; there are two suction pipes 6, which are respectively arranged on the front and rear sides of the base 1, and are located on the side of the support roller 5 away from the central axis of the packaging film 3, the suction pipe 6 has a suction port 601, the suction port 601 is located below the side of the packaging film 3, and the suction pipe 6 is connected to an external negative pressure device.

[0040] When in use, take the packaging film 3 moving from left to right to between the two embossing rollers 2 for embossing as an example. The two cleaning belts 4 are arranged side by side front and back, and can be symmetrically arranged front and back about the central axis of the packaging film 3, so as to better achieve symmetrical flattening in the front and back directions and reduce the front and back deviation of the packaging film 3. When the two cleaning belts 4 rotate, the front cleaning belt 4 moves the bristles 401 to the front side when in contact with the packaging film 3, and the rear cleaning belt 4 moves the bristles 401 to the rear side when in contact with the packaging film 3, so as to achieve flattening on both sides and reduce the stacking wrinkles of the packaging film 3. At the same time, the bristles 401 can clean the upper surface of the packaging film 3, reduce the presence of debris, and prevent debris from being pressed on the packaging film 3. The suction pipe 6 is connected to an external negative pressure device for exhausting air. The suction port 601 can be located below the side of the packaging film 3. The side of the packaging film 3 can completely cover the suction port 601 or partially cover the suction port 601. There is a gap between the suction port 601 and the packaging film 3, and the support roller 5 supports the side of the packaging film 3, so that the side of the packaging film 3 forms a flattening pulling force toward the front and rear sides after being subjected to wind pressure.

[0041] The air suction port 601 can be rectangular to increase the stress-bearing surface of the packaging film 3. The air suction pipe 6 is located between the support pipe and the side of the base 1.

[0042] The upper side of the base 1 has an upper bracket, and the cleaning belt 4 can be cyclically rotated and set on the upper bracket. The two cleaning belts 4 can be synchronously driven by a driving motor, and can be driven by a gear box or a belt transmission mechanism. There may be no blind spot between the two cleaning belts 4 in the middle of the packaging film 3. The bristles 401 are made of flexible material and can be staggered at the center axis of the packaging film 3 to reduce the blind spot. For the sake of clarity, the bristles 401 on the cleaning belt 4 are simplified and do not represent the specific density, nor do they show the staggered state of the bristles 401.

[0043] The embossing roller 2 is a prior art, and an embossing roller 2 that can be moved up and down and is easy to replace can be selected to adapt to different production requirements.

[0044] Furthermore, the ends of the bristles 401 contain magnetic materials, and also include: a magnet 7, which is arranged on the base 1, below the packaging film 3, and below the two cleaning belts 4, and the magnet 7 is magnetically attracted to the magnetic material.

[0045] When in use, the packaging film 3 can be inspected for damage, which is helpful to improve the quality inspection of the packaging film 3 and thus ensure the embossing quality. The bristles 401 contain magnetic materials, which can be magnetically attracted to the magnet 7 on the lower side of the packaging film 3, so that the end of the bristles 401 is tightly attached to the packaging film 3, which can increase the downward pressure of the end of the bristles 401 on the packaging film 3, improve the cleaning power, and improve the effect of flattening to both sides; when there are pores on the packaging film 3, the end of the bristles 401 can penetrate the pores and abut against the magnet 7 under the suction of the magnet 7. At this time, the packaging film 3 and the cleaning belt 4 are both in motion, and the bristles 401 that penetrate the pores can cause a small degree of damage to the pores, so that the pore defects that are not easily detected can be easily observed by workers.

[0046] The magnet 7 can be located below the area of ​​the packaging film 3 that needs to be detected, or it can completely cover the packaging film 3. The magnet 7 can be located between two support rollers 5, or it can be located next to the support roller 5 (still located below the cleaning belt 4, and the support roller 5 can be axially shorter than the belt) to ensure that the packaging film 3 can be completely covered.

[0047] The bristles 401 contain magnetic materials, which can be mixed into the bristles 401 by making materials, and mainly concentrated at the end of the bristles 401 close to the packaging film 3. It can also be achieved by embedding magnetic materials such as iron sheets, iron powder or magnetic sheets inside the bristles 401.

[0048] Furthermore, it also includes: an illumination lamp 8, which is arranged on the base 1 and located above the packaging film 3, and the illumination lamp 8 is located between the cleaning belt 4 and the embossing roller 2; a photosensitive device 9, which is arranged on the base 1 and located below the illumination lamp 8, and the packaging film 3 is located between the illumination lamp 8 and the photosensitive device 9.

[0049] When in use, after detecting the presence of pores on the packaging film 3, detection can be performed with the aid of the photosensitive device 9. The photosensitive device 9 can detect the intensity of the light from the illuminating lamp 8 after passing through the packaging film 3, and can use the normal and intact packaging film 3 as a reference. When pores appear and are enlarged by the bristles 401, a large amount of light directly passes through the packaging film 3, and the result of the detection by the photosensitive device 9 changes greatly compared to the reference, and damage can be automatically determined. An alarm or a mark record can be made with the aid of an alarm device or a processor.

[0050] Further, it also includes: a mounting frame 10, which has two mounting frames 10, which are slidably arranged on the front and rear sides of the base 1, respectively, and two support rollers 5 are respectively arranged on the two mounting frames 10, and the support rollers 5 are slidably arranged on the base 1 through the mounting frames 10. The mounting frame 10 has a mounting hole 1001, and the suction pipe 6 is inserted and arranged in the mounting hole 1001.

[0051] When in use, the support roller 5 and the suction pipe 6 slide forward and backward following the mounting frame 10 , and the distance between the front and rear centers can be adjusted to accommodate packaging films 3 of different specifications, so that the side of the packaging film 3 is located above the support roller 5 and the suction port 601 .

[0052] Furthermore, it also includes: two limiting rollers 11 , which are arranged vertically on the base 1 and located on the left side of the cleaning belt 4 , and the packaging film 3 passes between the two limiting rollers 11 .

[0053] When in use, the limiting roller 11 is located at the far left, the packaging film 3 enters between the limiting rollers 11, and then enters under the cleaning belt 4 to be flattened. The limiting roller 11 can be set to rotate, and the clamping packaging film 3 can limit the packaging film 3 in the front and rear directions, reducing the front and rear direction deviation of the packaging film 3 caused by the cleaning belt 4.

[0054] Furthermore, it also includes: a limit plate 12, which has two limit plates 12, and the two limit plates 12 are slidably set on the front and back sides of the base 1 respectively, and the limit plates 12 are located between the lighting lamp 8 and the embossing roller 2. The two limit plates 12 slide closer to each other and then move away from each other.

[0055] When in use, the limiting plates 12 on the front and rear sides can limit the packaging film 3 to reduce the deviation of the packaging film 3. The limiting plates 12 can be a "T"-shaped structure, close to or slidingly abutting against the side end surface of the packaging film 3.

[0056] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
